The Fire Wire is a sleek, high-tech tool with a slender, elongated body made of a lightweight, heat-resistant alloy. Its surface features a combination of smooth, polished sections and textured grips for secure handling. The wire itself emits a faint, pulsating orange glow, suggesting contained thermal energy, with intermittent sparks dancing along its length. The ends are equipped with sharp, conductive prongs designed to latch onto metallic surfaces or robotic creatures, delivering a controlled burst of heat.
